摘要： 对无取向硅钢常化态板材经过异步轧制,轧制速比为1.06,经过一次冷轧到0.5 mm厚,压下率为77.3%,并在保护气氛下进行再结晶退火,考察了异步冷轧织构和再结晶织构形成及演变.常化态板材的初始织构组分以{110}和{113}织构为主,异步冷轧织构主要是由α织构和γ织构组成,快慢辊侧的织构类型没有变化,但慢辊侧α织构和γ织构的取向密度明显高于快辊侧;再结晶退火后α织构取向密度明显减弱,而γ织构的变化主要是{111}〈110〉织构组分的取向密度减弱,{111}〈112〉织构组分的取向密度加强.

Abstract: The asynchronously cold-rolling texture and formation of recrystallization texture and its evolution were investigated for the 3% non-oriented silicon steel sheet after normalization, to which the rolling speed ratio was 1.06 and thickness was 0.5 mm as cold-rolled just once with 77.3% reduction. The recrystallization annealing of the sheet was done under atmosphere protection. The original texture components of the normalized sheet is mainly the {110} and {113}, while the asynchronously cold-rolling texture is mainly the α and γ. There is no texture type change beside the fast and slow rolls, but the orientation density of α and γ textures is much higher on the side of slow roll than on the side of fast roll. After recrystallization annealing, the orientation density of α texture decreases significantly, while for γ texture the orientation density of {111}<110> texture decreases but that of {111}<112> texture increases.
